A number is selected from first 25 natural numbers. What is the probability that it is a multiple of 3

multiple of 3 in 25 natural numbers are- 3, 6 , 9 , 12, 15, 18 , 21, 24

So probability is 8/25

Hope u get it.

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
